COMBINED MUSIC STAND AND CASE.

Specification of Letters Patent.

Patented Nov. '7, 1916.

Application filed March 8, 1915. Serial N 0. 13,065.

To all whom it may concern:

Be it known that I, CHRISTIAN M. ENGE- BRETSON, a citizen of the United States, residing at Starbuck, in the county of Pope, State of Minnesota, have invented certain new and useful Improvements in Combined Music Stands and Cases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combined music stand and case.

The primary object of the invention resides in the provision of a device which when extended will form a music stand and which when folded constitute an exceedingly neat and compact case in which the movable parts of the stand will be located.

With this and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

Referring to the drawing: Figure 1 is an elevational View of my device when the parts thereof are extended for use as a music stand.

Fig. 2 is a similar view showing the parts folded. Fig. 3 is a longitudinal sectional view, showing the position of the several parts when they are in such position as shown in Fig. 1. Fig. 4 is a similar view when the parts bear the relationship shown in Fig. 2. Fig. 5 is a fragmental. detail of the desk. Fig. 6 is a fragmental detail showing the manner of mounting. the desk in the inner tube. Fig. 7 is a fragmental detail showing the manner of mounting the legs. Fig. 8 is a bottom plan view when the legs are extended. Fig. 9 is a similar view of the locking plate removed. Fig. 10 is a vertical sectional View of the desk. Fig. 11 is a horizontal sectional view on line 11-11 of Fig. 4. Fig. 12 is an elevational detail, showing the music desk started to its folded position.

Referring to the drawing wherein like parts are indicated by like characters throughout the several views :In the embodiment of my invention shown, I have disclosed a desk indicated generally by the reference letter A and a standard indicated by the reference letter B. This standard consists of a tubular casing 15 which forms the upper end of the standard and a second tubular member 16. These members are hinged together, as at 17, and are maintained in alinement by means of a spring 18 which is mounted on the member 15 and engages a lug 19 on the member 16. In order that this standard may be maintained in a vertical position, I have provided a plurality of legs 20 which are secured to a sliding plug 21 in the member 16 and extend outwardly through radial slots 22 in the tubular member 16. This plug 21 is normally pressed outwardly by a coil spring 23 which is secured thereto and to the upper end of the member 16. In order that the legs 20 may be locked in their extended positions, I have rotatably mounted on the bottom of the member 16 a look ing plate 24 which has a plurality of radially extending slots 25 therein which have off-set portions 26. lVhen the legs extend outwardly from the member 16 they are locked in the offset portions 26 of the slots 25 in the locking plate 24: so that they are prevented from moving inwardly into the member 16 as will be obvious.

In order that the plug 21 together with the legs 20 may be maintained in the member 16 against the tension of the spring 23, at the Will of the operator, I have provided a locking pawl 27 which engages a shoulder 28 on the plug 21 and prevents the same moving outwardly. The pawl 27 is held in released position by means of a ring 30 rotatably mounted on the tube 16 and having an offset portion 27. hen the pawl 27 has one end disposed'in the offset portion 27 said pawl is in looking position as clearly shown in Figs. 4 and 11. In releasing the pawl same is manually manipulated to the flexed position shown in Fig. 3 and the ring 30 rotated to dispose the offset portion 27 out of line with the pawl 27 when the latter will be held in released position.

Mounted within the member 15 of the standard B is a tubular member 28 in which is slidably mounted a socket member 29. It will be noted that the members 15 and 28 are held in various adjustments by friction. This socket member is normally pressed outwardly by a coil spring 30 in the member 28', but is limited in its outward movement y a pin 31 sliding in a slot 32.

Iivotally mounted within the socket member 29 on the pin 31 is an upwardly extend- 7 ing arm 34 which has on the lower end the upper .and lower ends of the arm 34 are arms 41 which extend outwardly in opposite directions and are secured together at their outer ends by bars 42 which are pivotally secured thereto. Pivoted to the extreme upper end of the strip 37 are brace bars 43 which are in turn pivoted, as at 44, to the lower arms 41 between their ends. The construction which I have justdescribed forms the music desk A. In operation when it is desired to push the desk A within the member 15 of the standard B the strip 37 is pulled upwardly against the tension of a spring 44 secured to the lower arms 41 and tending to hold the desk open, at which time the arms 41 and the bars 42 and 43 will be simultaneously moved into substantial alinement with-the arm 34. The folded desk is then pushed downwardly against the tension of the spring 32. In

order that the desk may be maintained within the member 32, I have provided on the upper end of one of the bars 43 a projection 45 which when located within the member 32 is engaged by a latch member 46 which is locked in position by a clip 47.

Thus it will be seen that both the desk and legs may be folded, the desk pushed into the member 32 which is locked in the member 15 of the standard B and the legs into the member 16 of the standard B. After the operation of pushing these members into their respective casings has been accomplished the spring 18 may be disengaged from the pin 19 and the members 15 and 16 of the standard B swung about the hinge 17 as a pivot so as to lie substantially parallel. In order that the ends of these members 15 and 16 may be covered, I have pivoted to the lower ends of the members cent ends of the said members and is maintained in such position by the engagement of. the clip 50 thereon with the pin 19 on the member 16, while the cap 49 is swung over the adjacent ends'of the said members 15 and 1G and maintained in such position by the engagement of the clip 50 with a pin 51 on the member 28, which pin is provided for the-purpose. Secured to the member 15 is a suitable handle 53 by means of which the device may be carried when folded. 7 From the foregoing description it will be seen that I have provided a device which comprises such parts that it may be unfolded and will then constitute a complete music stand, but which When folded will constitute an exceedingly neat package wherein the movable parts such as the legs and the desk are located within two casings which form the standard of the device. I

have so constructed the device that the legs and desk will be automatically projected from the standard in which they are located upon the release of the locking means by the operator.

\Vhile I have-illustrated and described a particular embodiment of my invention, I have merely done so for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made within mentioned member, a spring for forcing the block toward the lower end of the member, a locking plate rotatably mounted on the lower end of the tubular member adjacent the legs, the said plate having a plurality of radially extending slots through which the legs extend and offset portions in the slots, the said plate being arranged by its rotation on the lower end of the standard to maintain the legs in their extended positions when the legs are located in the offset portions of the slots.
